LOUIS PIRO, OF. PHILADELPHIA, PENNSYLVANIA SPIGOT Application filed October 13, 1931. Serial No. 568,551.

My invention relates to a new and useful spigot which is provided with a self-cleaning internal strainer interposed between the mixing valve and the outlet of the spigot,

in such a way that the cold or hot water or the mixture of cold and hot water is passed through suitable screens to filter the water from any dirt or sediment therein, the strainer being so positioned that the 0 mere flow of'the water therethrough serves to keep the screen elements thereof constantly clean at all times.

My invention further relates to a novel spigot wherein I provide a strained soap 5 supporting receptacle which communicates directly with the drain or waste outlet which also communicates with the strainer in the spigot proper, said drain or waste outlet being readily accessible for flushing or My invention still further relates to a spigot of this character wherein the outlet or nozzle member is of the rotatable and easily detachable type to permit removal and reinsertion of the screens for replacement or repair.

My invention still further relates to a is provided with a mixing chamber for the mixing of the hot and the which mixing chamber communicates with the nozzle or outlet through a strainer composed of two screens, the innermost of which is of a relatively large mesh to retain relatively large particles, while the 3 outer screen is of a relatively small mesh to strain or filter out the smaller particles.

My invention still further relates to various other novel features of construction and advantage, all as hereinafter described and claimed in connection with the accompanying drawings, in which:

Figure 1 is a front elevation of a spigot embodying my invention.

Figure 2 represents a section on line 2-2 of Figure 3.

Figure 3 represents a section on line 3-3 of Figure 1.

Figure 4: represents a section on line 44 of Figure 3.

snugly Within the corresponding seat 26 Figures 5' and 6 represent fragmentary sectional views showing details of construction of the strainer.

Figure 7 represents a side elevation of the strained soap support or box forming part of my invention.

Referring to the drawings, in which like reference characters indicate like parts, 1 and 2 represent inlet pipes of any suitable construction for d livering cold and hot;

water, said pipes being connected to the sources of cold and hot water'supply in any suitable manner. The pipes land 2 enter the casing 3 at opposite points through the openings at and 5 which lead into the chambers 6 and 7. The chambers 6 and 7 are provided with the revolving valves 9 and 10 which are provided with the stems 11 which are adapted to be engaged and turned 13 (see Figures 1 by the handles 12 and and 4) a The chambers 6 and 7 communicate with the common mixing chamber 15 which communicates through the inner coarse screen 16 and the outer fine screen 17 with revoluble within the chamber 19 and is retained in position by the nut 20 engaging the stem 21 which extends upwardly through an opening 22 in'the front extension 23 of the casing 3. In the opening 22 is con-- fined a spring 24 which tends to maintain the nozzle 18 in its uppermost position with the enlarged hub portion 25 thereof fitting 1n the casing extension 23, as will best understood fromFigure 2. Communicating with the common mixing chamber 15 is the waste outlet which leads into the constantly open end 31 of the discharge nozzle 32 which pours into the drain or Waste pipe 33. The small-opening 31 at the end of the waste outlet 30 permits the escape into the drain pipe 33 of the smaller particles of dirt and sediment, the larger particles being unable to pass through the opening 31. The outlet 31 is formed between the head 37 which abutsagainst the shoulder 39 and which is tensioned by the spring 38 through the plug 34 and is provided with .the nozzle or outlet 18. The nozzle 18 is -7 a knob 40. The plug 34 threadedly engages the casing 3, as shown in Figure 2. When the water pressure in the chamber 15 becomes excessive, due to the clogging of the opening 31, with or without the simultaneous clogging of the screens 16 and 17 the head 37 is pushed outwardly against the tension of the spring 38 to enlarge the normally small openings 31 to permit free communication between the conduit 30 and discharge outlet 32, thereby permitting the larger particles of dirt or sediment which clog the opening 31 and cause the excess pressure to pass into the drain 33, the head 37 being pushed back by the spring 38 to its normal closing position to reduce the size of the opening 31 to that shown in Figure 2 immediately upon the flushing of the con duit 30 and the return of normal pressure in the mixing chamber 15. From this it will be apparent that my novel spigot is selfcleaning and self-flushing, and that it is entirely automatic in its operation, requiring no personal attention. When it 1s de sired to have access to the head 37 or spring 38 or their surroundings, it is merely necessary to unscrew the plug 34 and remove the stem 36 and its adjuncts. Similarly, if for some reason the spring 38 fails to function, due to any inaccuracy in its adjustment with respect to the water pressure or due to variation in the water pressure, the flushing or cleansing of the spigot can be accomplished by merely pulling outwardly on the knob 40 to withdraw the head 37 outwardly against the tension of spring 38, so that my novel spigot may be flushed by manual operation or may be left to its own automatic action, as may be desired. 42 designates a vertical opening which communicates with the discharge outlet 32 and which is adapted to receive and engage the bottom threaded end 43 of the pipe 44 which carries at its upper end a box 45 provided with a cover 46 hinged at 47. Within the cover 46 is positioned the screen 48 on which the soap and washrag used could be positioned, and in that way the soap and washrag are kept dry at all times, the moisture being permitted 7 to drain through the pipe 44 into the discharge outlet 32 and the waste or drain pipe 33. The soap box 45 is so positioned as to overhang the casing 3 thereby to support the soap in a readily accessible manner with respect to the spigot, thereby eliminating the necessity of pockets in the bathroom wall, where the soap is usually kept, and similar other disadvantageous constructions. The screens 16 and 17 are substantially concentric and are enclosed within a frame 49 which serves as a support therefor, and which is provided with beveled edges 52, so as to be wedged into a corresponding beveled edge opening leading from the mixing chamber 15 to the nozzle 18, as will be best underters Patent is:

stood from Figures 2, 3, 5 and 6. 55 designates ornamental caps or coverings which are threadedly secured to the casing 3 at 56 over the valves 9 and10 which serve to im prove the appearance of construction and which may be unthreaded to afiord access to the valves 9 and 10 and the internal construction. The operation is as follows: By manipulatingthe handles 12 and 13 it is possible to close or open to any desired extent either of the openings 4 and 5 com municating with the hot and cold water pipes 1 and 2 to secure the desired temperature of water. 'The operation of the valves 9 and 10 is illustrated in Figure 3, wherein the opening 4 communicating with the left hand pipe 1 is entirely closed, while the opening 5 communicating with the'right hand pipe 2 is entirely open. Water flowing from either or both of the openings 4 and 5 flows into the common mixing chamber 15 which communicates with the nozzle 18, through the double screen arran ement 16 and 17 above referred to.- The se iment or other solid matter contained in the water is retained by the screens 16 and 17 and only the filtered water is allowed to pass through the nozzle 18. The mixing chamber 15 communicates with the waste outlet 30 on the inner side of the screens 16 and 17, and the mere impact of the water against'and its flowing through the screens tends to produce a self-cleaning effect upon the screens, so that any sediment that may be stopped, thereby is immediately washed therefrom downwardly into the waste outlet 30, there'- by keeping the screens clean at all times.

Having thus described my invention, what I claim as new and desire to secureby Let- 1. A spigot comprising a plurality of water inlets leading into a common mixing chamber, valves for controlling saidinlets, a discharge nozzle communicating with said, mixing chamber, a plurality of screens of varying mesh interposed between said mixing chamber and said nozzle, a waste outlet, a conduit leading from said mixing chamber to said waste outlet, and means for normally; closing all but a small portion of said conduit.

2. A spigot comprising a plurality of water inlets leading into a common mixing chamber, valves for controlling said inlets,r a discharge nozzle communicating with said mixing chamber, a plurality of screens of varying mesh interposed between said mixing chamber and said nozzle, a waste outlet,
